WitrynaKawasaki dynamics of a classical Ising chain coupled to a thermal bath. The Hamiltonian is ob-tained for the general disordered case with non-uniform Ising couplings. The quantum spin chain (dubbed Ising-Kawasaki) is stoquastic, and depends on the Ising couplings normalized by the bath’s temperature. We give its exact … WitrynaThe 2D Ising model refers to a 2D square lattice with spins on each site interacting only with their immediate neighbors. The Hamiltonian of a system is, where is the …

Witryna12 kwi 2024 · We found that the ladder with equal coupling in legs has the maximal size of this plateau at the same coupling in rungs (the case J 1 = J 2 = J 3). For Heisenberg-Ising mixed spin ladder model, we found the appearance of two intermediate magnetization plateaus at low temperatures and some values of coupling parameters. Witryna21 mar 2024 · Figure 3: An example Ising quantum computer, described by indicating the strengths of the Ising couplings (measured in Hz) between all pairs of qubits; these couplings were chosen arbitrarily. The first part of the circuit is simple: the system begins with all coupling angles set to zero, and the first single-qubit gate has no … safeway weekly ad this week loveland co
